About Anzelmo

Anzelmo Ibogaine is a private, medically supervised center supporting executive-level ibogaine retreats with clinical oversight and discretion.

Thom Leonard is the founder and program director of Anzelmo Ibogaine. His role is operational and hands-on, centered on program structure, medical standards, and the consistent execution of Anzelmo’s executive retreats.

Originally from Chicago, Thom’s background includes firsthand experience with addiction and recovery, which led him to work with ibogaine both personally and professionally. In 2016, he co-founded the Ibogaine Institute, which evolved into Anzelmo Ibogaine in 2017. Since that time, he has remained actively involved in the daily oversight of medically supervised ibogaine programs in Mexico.

In addition to the executive retreats described on this site, Thom and the medical team also operate an ibogaine center focused on addiction treatment, where much of the team’s hands-on experience with ibogaine is developed and maintained.

While Anzelmo’s executive retreats are not designed for addiction treatment, the screening protocols, medical safeguards, and operational standards used here are informed by that depth of clinical experience. The intent is not rehabilitation, but to provide a controlled, professionally held environment for high-functioning individuals seeking clarity, recalibration, and perspective.

Public discussion around ibogaine has appeared within established research and media-adjacent organizations, including coverage referenced by the Multidisciplinary Association for Psychedelic Studies (MAPS), reflecting broader interest in its potential role where conventional approaches fall short. In addition, Thom has participated in professional conferences focused on plant medicine, safety, and responsible program design, including the Plant Medicine Conference.

Thom approaches ibogaine without mythology or exaggeration. He views it as a demanding tool that requires preparation, medical oversight, and responsible integration—particularly when used outside of addiction contexts. Anzelmo reflects this philosophy through limited attendance, infrequent retreats, and a clear emphasis on discretion and accountability.
